Schuh- und Zugantrieb für Zubehörteile von ModelleisenbahnenShoe and train drive for model railway accessories
Die Erfindung bezieht sich auf einen Schub- und Zugantrieb der im Oberbegriff des Anspruches 1 genannten Art. Schub- und Zugantriebe dieser Art sind im Handel. Bei einem solchen Antrieb ist die Gewindespindel mit dem Zahnrad fest verbunden und der Querbolzen weist das Muttergewinde auf. Bei Antrieb des Zahnrades i'urch den Motor v/ird die Spindel gedreht, wodurch der Querbolzen zu einer Längsbewegung veranl^nst v/ird. Um solche Antriebe billig herstellen zu können werden als Spindel Gewinde stangen in abgepassten Längen ve rv/=ndet, welche nicht sehr präzise sind. Wegen der kurzen achsialen Ausdehnung des Querbolzen in Spindellängsrichtung hat das Kuttergewinde in dem Bolzen nur eine kurze geführte Länge. Da vom Bolzen die Zug- und Schubkraft abgegeben v/ird, neigt dieser bei ungünstiger Befestigung der" Kraftübertragung zum Verks.nten. Als _FoIge dieser Eigenschaften entsteht im Betrieb häufig ein'.· zitternde Bewegung des beweglichen Teiles. Aufgabe d'er Erfindung ist es, einen in seiner Bauweise kompakten Antrieb zu schaffen, der trotz Verwendung wenig präziser Bauteile "eine zuverlässige unc1 ruhige Bewegung gewährleistet. Die Aufgabe vird durch die im kennzeichnenden Teil de« Anspruches 1» genannte Merkmale- «relönt.The invention relates to a push and pull drive of the type mentioned in the preamble of claim 1. Push and pull drives of this type are commercially available. In such a drive, the threaded spindle is firmly connected to the gear and the cross bolt has the nut thread. When the gear is driven by the motor, the spindle is rotated, causing the cross bolt to move longitudinally. In order to be able to manufacture such drives inexpensively, threaded rods in adjusted lengths are used as spindles, which are not very precise. Because of the short axial extension of the cross bolt in the longitudinal direction of the spindle, the cutter thread in the bolt only has a short guided length. Since the tensile and thrust force is given off by the bolt, it tends to warp if the force transmission is not properly secured. As a result of these properties, the moving part often moves in a trembling manner during operation. The object of the invention is to create a drive that is compact in its design and that ensures reliable and smooth movement despite the use of less precise components. This object is achieved by the features mentioned in the characterizing part of claim 1.
r.p.durch daß boim Anspruchsgegenstand die Spindel nicht gedreht wird, sondern stillsteht entfallen Zitterbewegungen, die Hurch unrunden Lauf von Gewinn«stangen und Rauhigkeit im Gewinde beim Stand der Technik entstanden war°n. Auch dip Gefahr eines Verkantens des Bolzens un<· nines damit verbundenen schwergängigon Laufes ist nicht mehr gegeben, -&iacgr;^ Lager können einfach ausgeführt nein, da sie abgesehen vom achsialen Führen <&lgr;$&ngr; Matter keine rotierende Bewegung aufzunehmen haben und eigentlich nur v)<-r Längs.führung der ;;pind^l dienen.Because the spindle in the subject matter of the claim is not rotated but remains stationary, there is no longer any shaking movement that was caused by the uneven running of the winning rods and roughness in the thread in the prior art. The risk of the bolt jamming and the associated stiff running is also no longer present, and the bearings can be designed simply, since apart from axial guidance they do not have to absorb any rotating movement and actually only serve to guide the spindle longitudinally.

Auf einer a. B. äüs Kunststoff gegossenen oder gepreösten Bodenplatte Ö ist ein handelsüblicher Elektromotor 1 befestigt, z. B. aufgeklebtj„ welcher ah seiner Welle eine Schnecke tragt* Eine Gewindespindel 4 ist längsbeweglich in wenigstens 2 Lager 5,6-, geführt, aiii Ende eier Bödenplatte kann ein drittes Lager 7 vorgesehen sein« A commercially available electric motor 1 is attached, e.g. glued, to a base plate made of plastic, which has a worm on its shaft. A threaded spindle 4 is guided longitudinally in at least 2 bearings 5, 6, and a third bearing 7 can be provided at the end of a base plate.
Mit der Sohnecke 2 steht ein Zahnrad 3 in Eingriff dessen Aehsbohrung als Gcwindomutter 3 a ausgeführt ist. Die Gewindemütter 5 a ist auf die Spindel 4 aufgeschraubt. Auf der Spindel ist ein " Querbolzpn 8 befestigt z. B. geklebt, der mit seinem einen Ende in ein Langloch 9 in der Bodenplatte 0 gre-ift und Io die Spindel gegen verdrehen sichert.A gear 3 is engaged with the corner 2, the outer bore of which is designed as a threaded nut 3a. The threaded nut 5a is screwed onto the spindle 4. A cross bolt 8 is attached (e.g. glued) to the spindle, one end of which engages in an elongated hole 9 in the base plate 0 and secures the spindle against twisting.
Weiter sind auf der Bodenplatte Ö veningstens 2 Endkontaktschalter 1o, 12 aufgebaut, welche vom Querb'olzen betätigt worden können. Einer ( 12 ) ist fest montiert, der andere ( 1o ) zum Einstellen der gewünschten Länge der Schub- unci Zug&swegung in Längsrichtung der Spindel verschieblich angeordnet, er kann in ein Langloch 13 mit einer Schrauben-Mutterverbindung beliebig montiert werden. Die Enrtkontaktschalter dienen der_Endabschaltung *dns Motors bei Erreichen der Entstellung der Bewegung und d,er .Rückmeldung. Gegebenenfalls kann auf eine der beiden ein Weiterer Bndkontaktschalt&r ( 11 ) z.~~B. zum Umschalten der Polarität des Herzstücks einer Weiche vorgesehen sein (nicht dargestellt). Zur Übertragung eier Zug- und Schubbewegung auf das zu bewegende ■Teil können am Querbolzen an beliebiger Stelle Gewindcbohrunger. vorgesehen sein zum anbringen entsprechender Übertragungsglieder ggf. auch des zu bewegenden Teiles selbst.Furthermore, at least 2 end contact switches 10, 12 are installed on the base plate Ö, which can be operated by the cross bolt. One (12) is permanently mounted, the other (10) is arranged to be movable in the longitudinal direction of the spindle to set the desired length of the push and pull movement; it can be mounted in any position in an elongated hole 13 with a screw-nut connection. The end contact switches are used to switch off the motor at the end of the movement and to provide feedback. If necessary, another end contact switch (11) can be provided on one of the two, e.g. to switch the polarity of the frog of a switch (not shown). To transmit a push and pull movement to the part to be moved, threaded holes can be made at any point on the cross bolt. be provided for the attachment of appropriate transmission elements and, if necessary, also of the part to be moved itself.
Ebenso kann die Kraftübertragung &ggr;&ogr;&eegr; irgendeiner Stelle z. B. den Enden der Spindel erfolgen.Likewise, the force transmission can take place at any point, e.g. the ends of the spindle.
